A method for assessing the structure parameters of porous ceramic materials by porosity and particle size is presented. Based on it, a physically more rigorous than the well-known Cozeny formula is obtained, a formula for determining the average (hydraulic) radius of the capillaries of permeable materials. The presented results of the calculation of the average radius of the capillaries of porous ceramics based on electrocorundum according to the obtained formula are in better agreement with experimental data than the calculations by the Cozeny formula.

单组分陶瓷多孔结构和渗透性参数的估计

提出了一种通过孔隙率和粒径评估多孔陶瓷材料结构参数的方法。基于此，获得了比众所周知的Cozeny公式更严格的物理公式，该公式用于确定可渗透材料的毛细管的平均（液压）半径。根据所获得的公式计算得出的基于电刚玉的多孔陶瓷毛细管平均半径的计算结果与通过Cozeny公式进行计算的实验数据更加吻合。
